   7             Simple test program for I2C (24C64) library.
   8          
   9             Connect a 24C64 to the SDA and SCL pins described 
  10             in the library file (I2C_Core.C).
  11          
  12             Terminating resistors not generally required on the bus.
  13          
  14             Pull all three address lines (on the EEPROM) to ground.
